Annoyed 😒

So my period was supposed to start yesterday and ofc nothing so today I went to rite aid and got a pregnancy test but it already had a negative line in the result window I took it anyways and it came back negative. My breast isn’t sore or anything I have been nauseous but it’s been mild should I take the test back and get a new one or Im just tired of trying im really over spending money on test for nothing
